OEM Custom Black Wire Mesh Cloth for All Kinds of Plastic Industry Melt Filtration Work

OEM Black Wire Mesh Cloth is a type of woven filtration mesh made from high-quality low carbon steel wire. It is commonly used in plastic extrusion systems as a filter medium to remove impurities from molten polymers such as PP, PE, PVC, and ABS.

Due to its dark surface color after heat treatment, it is widely known as “black wire cloth” or “black iron wire mesh.” This material offers excellent mechanical strength, stable structure, and cost efficiency, making it a preferred choice for industrial filtration applications.

It can be supplied in rolls, sheets, or die-cut filter discs according to OEM requirements.

Key Features

• ▪ Stable woven structure with uniform mesh opening
• ▪ High tensile strength and wear resistance
• ▪ Excellent filtration efficiency for polymer melt
• ▪ Cost-effective alternative for industrial filtration systems
• ▪ Suitable for continuous extrusion production
• ▪ OEM customization available (size, shape, mesh count)

Applications

Black wire mesh cloth is widely used in industrial filtration, especially in plastic and rubber processing industries:

• ✔ Plastic extrusion filtration (PP, PE, PVC, PS) 
• ✔ Plastic recycling and granulation systems
• ✔ Melt filtration in extrusion machines
• ✔ Rubber and polymer processing
• ✔ Chemical and petrochemical filtration

FAQ

Q1: What is black wire mesh cloth used for in plastic extrusion?

A: Black wire mesh cloth is used as a filtration medium in plastic extrusion machines. It helps remove impurities, unmelted particles, and contaminants from molten plastics such as PP, PE, PVC, and ABS, ensuring smoother extrusion and better final product quality.

Q2: Can black wire mesh cloth withstand high temperature in extruder machines?

A: Yes. It is designed for standard plastic extrusion processes. It can withstand typical operating temperatures of polymer melting (commonly 160°C–300°C depending on material). However, it is not suitable for extremely corrosive or highly acidic environments.

Q3: What is the difference between black wire mesh and stainless steel mesh?

A: Black wire mesh (carbon steel) is more economical and suitable for general plastic filtration. Stainless steel mesh offers higher corrosion resistance and longer service life but at a higher cost. Customers usually choose based on budget and application requirements.

Q4: What mesh size is suitable for plastic extrusion?

A: Mesh selection depends on filtration precision:

Coarse filtration: 10-20 mesh

Medium filtration: 30-60 mesh

Fine filtration: 80 mesh and above

For most plastic extrusion processes, 20-60 mesh is commonly used.

Q5: Can you provide custom sizes or OEM production?

A: Yes. We support full OEM customization including: Mesh count and wire diameter, Sheet size or roll width, Cut-to-shape filter discs, Multi-layer screen packs, Private labeling and packaging

Q6: Is black wire mesh reusable?

Yes, in some cases it can be cleaned and reused depending on contamination level. However, in high-efficiency production lines, it is usually replaced regularly to maintain stable filtration quality.

Q7: What industries commonly use this mesh?

A: It is widely used in: Plastic recycling plants, Plastic extrusion factories, Polymer processing industries, Rubber and chemical filtration systems, Pelletizing and granulation lines
